Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is connected to a pivoting vertical member and up to 20 feet long. Jib cranes can move loads between any areas within the boom's arc of rotation. Light duty models are used in warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website features the major types of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane units do not need any support from the building structure and can stand by themselves. The horizontal boom in this case is attached to a pivoting vertical column that is solidly anchored to the floor of the building. This kind of jib crane is able to rotate a full 360 degrees and needs a foundation made of either concrete or steel.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. These pivots are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the advantage of not needing the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom which is connected to the wall of a building rather than the normal vertical column. These machine are ideal in places where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type uses a tie rod from above the boom which is connected to the wall. The other type supports the boom from below by using a cantilever brace which is connected to the wall also.
